This is a hot-wire foam cutter I created last summer when I had a need to cut odd shaped pieces of styrofoam insulation. The stretcher assembly is made from pallet stringers and the base is just plywood and some pine that was laying about the shop. This project also has my first mortise & tenon joint (pic 3).
The guitar string wire is made “hot” using a 0-30V Lambda current-limiting power supply (pic 4) which I use for electrolysis too – which is why it is not hard-wired to the cutter.
As you can see in the last picture, the cut quality is very good. It sure beats any other method of cutting foam that I have tried. Easier, generally faster and a LOT less mess (none at all).
As always, any comments, good, bad or indifferent are welcome.
Thanks for looking.
